Animation binary The binary file representing the animation Please do take note that this binary creates the animation along with all of its children When switching binaries the process will create the new children but will not destroy the previous children 3 Sound group name Used to determine which sound group the animation should use in order to reproduce its sounds 4 Sound priority The priority of the sounds emitted by the animation 5 Preload sounds Used to determine whether the animation s sounds should be preloaded at startup or not It is to be noted that the relationships between symbols at the XFL project are directly related to the object hierarchy at the Unity project If the hierarchy were to be changed then the change must be reflected on the XFL project This also means that the user does not need to recreate the whole hierarchy out as long as the references exist on the XFL project then Flash to Unity will correctly generate each child animation Hierarchy coloring and tints This option is available for all animations imported into Flash to Unity but it s disabled by default because it is process intensive and may produce lag when not used sparingly in a game So far the only components that have it enabled by default are popups and loading screens which are not punished by the execution of hierarchy coloring This process allows for a parent animation to change the color of each of its children animations when
